RAIL-JOINT.

.exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to new and useful improvements in rail joints and the primary object of the invention is to provide a device of this character which will eliminate the use of bolts, nuts, fishplates and the like which are usedon most rail joints now in use.

Still another object of the invention re-' sides in providing a construction in connection with the rail sections which affords interlocking engagement between said sec-- tions.

A still further object resides in providing a simple, inexpensive and efficient con- In the accompanying drawing forming a art of this application :Figure 1 is a si e elevation of a device constructed in accordance with my invention and showing one rail section about-tobe applied to the other section.

rail sections which are adapted to be brought into abutting relation to one another and which are designed for interlocking engagement, each in itself forming a portion of my improved rail joint structure. The tread 3 of the rail section 1 terminates some distance short of the end of this section thus producing a web extension and the base flanges of this rail section extend to the end of the web. The web of this section is transversely enlarged in I thickness as indicated at 4 and this enlarged portion extends to a point a short distance beyond the end of the tread 3. This enlarged web portion 4, however, is slotted on each side of the web extension said slotted portions being indicated at 5 and the same extend to points a short distance under the tread 3. The opposite rail section 2, has the web thereof increased or enlarged transversely as seen at 6 such portion extending for the greater portion of its length, and the base flanges of this section terminate some distance short of the end of said section, thus forming a shoulder 7 for abutment against the. end of the section 1. The tread 8 of this rail section 2 .terminatesjust short of the end of the web of this section thus providing a terminal engaging portion of the web at. this section and the web of this section is slotted cen trally as shown at 9 whereby to receive the web extension of the first mentioned section 1 therein. By slotting the complete web as described, the projecting portions of said web form, as statedabove, terminal engaging portions indicated at 10 and these portions have the outer faces thereof slightly reduced whereby to be readily received in the slotted portions 5 of the first mentioned section. When so engaged, the outer faces of the web of the section 2 fitflush seen that when the two sections are brought together so that the web extension of the one section fits within the slotted ortion of the web of the other section, the t reads of the 1 rail sections will be brought inabutting re- In describing the invention I shall refer lation to onelanother to form substantially a continuous tread and the base flanges will also be brought into such relation as to form substantially continuous base-flanges of the formed but my invention primarily contemplates the provision of a means for locking the sections together automatically and providing a rail joint'as the result thereof. To

this end, the web oft-he rail section 1 at a point adjacent its outer end is provided with plate-like extensions indicated as 11. These plate-like extensions form locking lugs. or the like thereonthe same being formedinteg M with the faces of the web, and the inner directed edges of said extensions 11 are concaved as indicated at 12 while the outer directed edges thereof are convexed as shown at 13, the upper edges of these extensions 11 terminating justshort of the upper edge of the web extension. At predeterminedv points on the web of the section2, the walls of the 'slot therein are provided with grooves 14 which .form channel ways for'the reception of said plate-like extensions'll therein when said section 2 is applied to the section 1.

These grooves 14" are designed coincident to' .the outline of the projections 11 so as. to

readily receive the latter therein and when said projections are properly received. in saidg'rooves or channels, it is obvious. that said rail. sections will be interlocked one with the other. I

i p In operation, the rail section '2 is brought in relation with respect to the rail section 1 so as to receive therein the treadless web of the latter. In order to accomplish this result, the section 2 must be applied to the section- 1 from above and when so applied, the

. terminal "engaging portions of the section section 1 whereupon said section 2 is low-.

ered, said lowering being readily made-fpos sible through the beveling of the terminal engaging portions. In the loweringof this section 2 it will be seen that the projections 11 on the faces of the web sectionl'will be received in .the grooves or channels 14 of the slotted webzofsa-id section 2. When this rail section 2 has been lowered, the shortened base flange thereofwilljabut the base flangev Y ofthelrail section 1 and a completeirail will thus beformed, the sections of which are so I interlocked one with the other asto prevent any possible disengagement thereof. The interlocking of. the sections-of the rail is such i as to prevent any possible lateral or longiu tudin'al movementthereof and the abutment "between tlie'sections is 'so'close as to rovide a perfect fitting rail joint whereby t e usual 'creased transversely and slotted for a dpornoise incident to the rolling of cars over joints in rails willbe eliminated in the use of this device.

From the foregoing it will be seen that I have provided a simple, inexpensive, and efficient means for carrying out the objects of theinvention and while I have particularly described the elements best adaptedto perform the functions set forth, it is obvious that various changes in form, proportion and the minordetails of construction may be resorted to, within the scope of the appended claims, without departing from the spirit or sacrificing any of the principles of the invention.
